Abstract: The significance of promote high-efficiency motor and motor system in China was analyzed by

means of literature research，questionnaire survey and enterprise survey. Policies and measures for the promotion of high-efficiency motors and motor systems were sorted out. Conduct market research on high-efficiency motors and pumps，fans and compressors matched with high-efficiency motors that were shortlisted in “the national

recommended catalogue of industrial energy saving technology and equipment”in 2020 to analyze the production，sales and promotion statue of high-efficiency motors and pumps，fans and compressors matched with highefficiency motors. By using the system analysis method，it can be seen from the analysis that after being shortlisted in“the catalogue”，the main business income of each enterprise has increased significantly，among which the sales of grade I&II energy efficiency equivalent products have increased rapidly. According to the research，the overall evaluation on the promotion effect of high-efficiency motors and motor systems were carried out from the aspects of promoting the growth of energy-saving industry，improving the market share of energy-saving equipment，promoting the completion of energy conservation and emission reduction tasks. It will become basis for industrial energy conservation and green development，and forming a positive interaction with the preparation and revision of relevant standards.
